Canada Centennial 1867-1967 Medal Coin Set

i believe this is an after market set, I think the original coins were sold individually, in little snap cases. I however have never come across the set you have here. I know there were tons of the stamps issued and they are readily available on ebay. As far as the coins value I would guess between 60-95$ if sold individually , as a set not sure. I am positive there is just a base metal underneath the gold plating, no precious metals.. hope this helps a little.

Thanks for the replies. I was thinking that this was sort of an enigma. I'll do some further research too.
